Get matched with top arborists in Rochester, IL

Licensing requirements for arborists, also known as tree surgeons, vary by state and municipality. Many areas require a license, which often involves specialized education and experience. Even if not mandated, it's wise to hire a licensed professional as they tend to have more experience. Beyond licensing, look for certifications from organizations like the International Society of Arboriculture (ISA) or the Tree Care Industry Association (TCIA), as this indicates a higher level of expertise. Certified arborists must typically pass a comprehensive exam. Always confirm that the arborist has a business license and is fully insured to protect yourself from liability. Seeking positive recommendations from local homeowners is also a good step in finding a qualified professional.

Deciduous shade trees (the type of trees whose leaves fall off in autumn) need to be pruned in late winter—between February and March. That’s because it’s easier to find and remove sick or dead branches when no leaves are present. And wounds close and heal faster in colder temperatures so pruning them at this time also makes them less prone to infection.

You need to remove all branches affected by Dutch elm disease. If your tree has several affected branches, you will probably need to remove the entire tree.

Most plum trees are pruned into a vase or open wine glass shape. They’ll have a shorter central leader (the trunk) that supports three to four main branches. Of course, this isn't always the case. If you have a European plum tree, you can grow it in a pyramid shape. Let the central leader extend the length of the tree and prune smaller branches to create the pyramid.
